With world fish stocks dwindling, tilapia farming is a global success story, with production tripling this millennium.

This is now a $7.6bn industry, producing 4.5million tonnes of affordable high-quality fish every year. And it is sustainable, because unlike the salmon and sea bass we grow in Europe, tilapia don’t need to be fed lots of other fish caught from the oceans, but largely eat vegetable material and farmyard waste. Although now cultured throughout the world, tilapia originally come from Africa.
